DUMP CAR.

APPLICATION FILED JULY 15. I916- Patented Oct. 9, 1917.

2 SHEETS-SHEET 2- like, riveted or otherwise secured to the side stakes and reinforced along their upper edges by the angle bars These side walls 25 terminate above the underframe of the car, as clearly shown in the drawings,

having inwardly directed angle plates 25; secured to thelower edges thereof. The side walls are reinforced between. the'side StitliQS by vertically extending angle bars 26, whlch are riveted to the plates 25 andhave their inwardly directed, oppositely disposed flanges connected to the. transversely extending braces 25. Side dumping doors 27 of composite metal construction, are oat-i sides of the longitudinal sills 12, the inner and lower edges of the doors being arranged to terminate adjacent the edges of the plates 19 sothat a tight closure is formed. Z-bars or other suitable shapes 28 are attached to the inner and lower-edges of the doors 27 V and the lower flanges 28 of these plates have secured thereto the chains 29 which are wound upon the operating shafts 30 andsecured thereto by eye-bolts 30% These shafts 30 are mounted in suitable bearings r car ried by the center sills and other parts of the car underframe, and they extend longitudinallyto theend of the car. Each of the plates'19 has secured thereto an inverted angle iron member 31 which overlies, the adj acent longitudinally extending shaft 30 and which has aflange lying parallel to the web of the adjacent plate 28 when the dumping doors are in closed position. Sup porting members 32,] preferably of angle iron form, arerattached to the upper sides of the sills12 and extend upwardly andoutwardly to the side stakes24c, forming stops for the doors 27, and closing the spaces between adjacent doors 'whenfthe latter are moved to closed positions by the operation 'ofwinding the chains'29 upon the shafts'30 which form drumstherefor.

Downtvardly and inwardly inclined plates '33, lying in the same planes, as thedoors 27 I when the latter'are in closed positions, ex-

tend from the inclined'end walls "21 to the adjacent doors 27fand from the side walls 25v to the lonlgitudinal .sills, thus forming parts of the: hopper at the endsof the car."

Between the. sills 12 there is formed the lower portionfof the central longitudinal hopper which comprises the-downwardly and inwardly inclined 'fioor sectionv 35 and the'lsimilarly inclined dumpingdoors 36,

the floor section 35 being connected at its upper edge to the adjacent sill 12 and being supported at its lower edge by the supporting members 37,

which extendv upwardly and are secured to the transverse sills 16 of d the car. The centrally discharging dump 'ng doors 36 are hinged at their upper edges to-the adjacent longitudinal sill 12 by means of hinges 38, and the lower portions thereof are provided with brackets 39 whichare connected by means of eye-bolts -10 to the chains 11 which extend around the lower meeting edges of the dumpingdoors 36 andthe floor section'35 and thence upwardly beneath the floor'section 35 to the operating shaft :4 upon which' the chains are wound, and to whichthey'are secured by eye-,bo'lts45. The shaftt-is mounted on suitableibfearings t6 carried by'thej ad jacent' longitudinalsill 12 and other parts of the car structure, and it efttends';longitudinallyrof the car to the end sill 14 The operating shaft 44- and theoperating', shafts 30 are operated by meansof suitable lever and'ratchet mechanism 47, which may be of the form shown in Fig. for instanoe',,con1- prising a lever48 mounted on the rotatable operating shaft,a ratchet 49, and an oscil lating pallet 50 mounted-inabracketfil and guide 52 andhaving a securing'cam 5 3'. Themembers 51 and 52 maybe attached to a plate 54 carried by the end sill 1 1; It will be seen thatby means of the foregoingconstruction a car is provided having a hopper bottom which comprises the downwardly and inwardly inclinedend-walls 2 1,,

the downwardlyfand'inwardly inclined up} oo per or side dumping doors 27, the downwardly and inwardly inclined inner walls of the longitudinal sills 12, andthe downwardly and inwardly inclined floor sections I and central dumping doors Y35 and 36 re spectively. V This car, by'reason of the above described arrangement of doors, has the ad-' vantage that it permits the discharge of the contents of the car centrally between the.

rails andalso at the sides ofthecaroutside 'ble to discharge all of the load centrally between the rai1s, t0 discharge all of the load, a part between the rails, and' a partgat either'orboth sides of'the car,'-or substan tially the whole load maybe discharged at' the sides." "It "is oftentimes desirable; in bal- 7 last and construction work to discharge more material atone sideof the car thanat the other, as, for example, when ballasting a double track'road, it sometimes happens that it is desirable to discharge-more material at the side of the outer rail than be-' tween the inner rails of the double track, ,So, too, in construction work n filling e bankments. it is bitten desirable to depdsit the greater part of the load at one side or the other of the track. All of these func tions are performed by the car arranged as hereinbefore described.

Although I have shown and described a particular embodiment of the invention, it-

will be understood that it may be constructed in various other forms without departing from the scope thereof as defined in the appended claims.

I claim:

1; A car having a stationary central lonj gitudinal hopper, the sides of which are'in clined downwardly and. inwardly from the sides of the car, a hinged bottom door, and doors above said hopper hinged at their up per edges so asto swing outwardly, saiddoors forming when in closed position a portion of the hopper sides.

2. A car having a stationary longitudinal hopper the sides of which are inclined downwardly andinwardly from the sides of the car, ahinged bottom door, and doors above said hopper hinged at their upper edges and arranged to form a portion of the hopper sides when in closed position and to swing outward to dischargeat the sides of the car.

3. A car having a stationary longitudinal hopper with inwardly and downwardly inclined sides, a door for permitting downward discharge from the hopper, and doors above said hopper hinged at their upper" edges for swinging out to discharge at the sides of thecar and arranged to occupy in clined, positions andform continuations of the sides of the hopper when'in olosed'positi'on.

' Copies of this patent may be obtained for at. A ca'r having a stationary longitudinal hopper with inwardly and downwardlyiinolinedsides, a hinged bottom door for ,the hopper,- and doors above said hopper hinged at their upper edges and arranged to swing.

five cents each, by addressing t washingtomn'c. I

in and close to occupv inclined positions in continuation of the sides of thehopper, and to swing out to discharge the contents of the car at the sides.

5. A car having a longitudinal hopper with inwardly and downwardly inclined sides, a hinged bottom door for thehopper, and upper doors hinged at their upper edges to the sidesof the car and arranged to. occupy inwardly and downwardlyv in- 6. 'A car of the class described havingits. I body portion forming a hopper whose apex extends centrallyandlongitudinally of the bar, said hopper being provided with lower doors closing the hopper at the apex and with upper 'doors hinged at their upper j edges above the fixed side portions of the hopper, said upper and lower doors for m-.

a part of the sides of the ing when closed hopper. g H g V 7. A car of the class described having its body portion forming a hopper with its apex arranged centrally and longitudinally of the car, lower doors closing theapex of the hopper, and doorsin the sides ofthe hopper above the fixed portions thereof,

said doors in the sides of the hopper being supported wardly.
